WElGHlNG AND DUMPING MACHINE.

SPECIFICATION forming part of Letters Patent No. 283,641, dated August 21, 1883.

' Applicaiion filed June 6, 1863. (No model.)

To all whom, it inay concern:

Be it known'that I, JERRY MoRRoW, of Jackson, county of Jackson, State of Ohio, have invented a new and useful Improvement in a Combined WVeighingand Dumping Machines, of which the following is a specification.

. provided with a drop-bottom, whereby the coal may be dumped from the aforesaid weighbox to any'suitable place for transportation. It further consists'in the arrangement and combination of parts forthe accomplishment of these results.

In order that others skilled in the art to which my invention belongs may be able to make and use the same, I will proceed to describe its construction and operation.

In the first place the weigh-box a is suspended to the floor I) of the weighing-machine by means of rods 0 c. The brake-regulating mechanism (1 c is also attached to the'floor of the weighing-machine, in order that the weighing, holding, and braking mechanism shall work in unison. The brake is supported on the weigh-box a through the agency of uprights ff and framing g h. The brake, in this instance, is constructed with a drum, t, that is journaledto the aforesaid uprights, and two friction-clamps, Z Z, pivoted at m m, and capable of being opened or closed from or against the aforesaid drum by means of a lever, d, connectingrod n, and links q 1-. The lever d is provided with a lateral projection, s, that may be sprunginto or out of the notches t, that are formed around the periphery of the part c. The weighingmachine u 11 may be of any 111g and dumping apparatus of my invention.

desired construction, as my improved apparatus can be applied to any of these machines. The weigh-boX is properly braced together in the manner shown by the drawings, and its tilting bottom 10 is pivoted to it at x. To hold the bottom a; to its work I employ two ropes, y y, that are wound around the two sheaves, 2 Each of these cables or ropes is attached at one end to the free end of the bottom w, and at the other to a weight, a; To prevent the bottoms w from moving in an upward direction past the desired position, I use a check, 1;, that is fast to the end of the weighbox, and it is found preferable to have some elastic material between this check and the contiguous part of the bottom 10. The exit end of the Wei gh-boX is provided with an opening, a, through which the coal passes on its way to the transporting vehicle, car, or boat.

The operation of my apparatus may be briefly described as follows: \Vhen it is to be used at a coal-mine, the coal is dumped upon a stationary inclined screen, at, and while passing down this screen it is freed from slack, the slack falling through it to a place beneath. This screen is placed at a sufficient incline to insure the proper delivery of the coal to the weigh-box, and the drop-bottom w is placed nearly level, so as to break -the force of the falling coal and prevent its colliding with the end of the weigh box. Vhen a sufficient amount of coal has been dumped into the weigh-box, its weight is ascertained through the agency of the aforesaid weighing-machine, and the operator removes the projection s from the notches t, and the lever d is moved so as to lessen the friction between the pieces ZZand drum 1', and the bottom 10 is lowered by the gravity of the coal that is on it to the position indicated by dotted lines on Fig. 1 of the drawings, and the coal is discharged into astationary chute, e, from whence it can be discharged as desired. After the load has been thus removed from the bottom 20, the weights to a will cause the drum v3 and attached sheaves z z to revolve, and thereby return the bottom 10 to its place of rest.

With this apparatus coal can be handled very rapidly and with but little manual labor; besides, there will be a great saving in the breakage of coal by not allowing it to strike any fixed check-board. In addition to these advantages, not a single lump ofcoal can escape before being weighed, and none can remain on the drop-bottom after being weighed.

I-Iavingthus described myinvention, what I claim as new, and desire to secure by Letters Patent, is

1. A combined weighing and dumping apparatus, consisting oi'a weigh-box, a brake to regulate the descent of a drop-bottom, a chute to direct theinflow ofthe material tobeweighed, and a counter-weight to cause the return 01' said drop-bottom, the whole suspended from a stationary weighing machine.

2. The combination of the weigh-box suspended from a weighing apparatus and provided with a drop-bottom, with a weight at tached to a cable passing over a drum and connected with the free end of the tilting bot tom, abrake for acting on the drum to hold and release the same, and a hand-lever for actuating the brake, substantially as described.

3. The combination, with the box (a for re ceiving and holding the material, and a dropbottom, 10, pivoted at one end to the-under side of the box, a brake mechanism for regulating the descent of the free end of the dropbottom, a hand-lever for actuating the brake mechanism, and a counter-weight for closing the drop-bottom, substantially as described.

4-. A weigh-box, (1, provided with a dropbottom, 10, a drum and sheaves, i z, a brake mechanism, ropes or cables y 1 and counterweights (0 a, for the purpose specified.

5. A weiglrbox provided with a drop-bob tom and its brake mcclmnism, any suitable weighing-maehine, and a combined chute and screen, for the purpose spebiiied.

l'u testil'nony whereof I have hereunto set my hand this 30th day of April, 183.
